Impressive all the way around! But, how does the differential work?

Allan

How ya doin' Allan?
Very well to be honest. It does run smooth in and out of corners.
I can set the wheels with the screws up and after going round just 1 corner they screws don't line up any more.
The diff makes the 4WD work so much better.

:text-bravo: looking forward to more on this.

Nice, I like that 2 pinion diff. I'd bet it would even work noticeably better in just the two wheel drive mode.

Definitely one very interesting car, Dave. If you ever build another of those gear diffs, I'd like to see a "How-to" article posted here.:)

WOW! That is a very cool build! I like both the one off differential (I had looked at trying to retrofit something from the RC world a while back) and then tying it to independent front axles as well is pretty darn slick!
Thanks for sharing!

Very impressive design work.
I had to look for a bit to see how it all works and then noticed the second pinion.
Great process.

I like it!

Doesn't it feel great to be working outside the normal boundaries?

I for one enjoy uncharted territory.

On my large list of things to do is to change the Flat-6 motor in my Slot.It Audi R-18 e-tron quattro to a Flat-6 RS, which is a 25,000 rpm motor with 240 grams/cm of torque. With the all wheel drive I'm hoping to get the car to come out of a corner hard, very hard.

Looking forward to hearing more about your project.

Wow Dave that is impressive
I have thought of doing a diff in a rear wheel drive car but was not sure on how to go about it
A how to would be great

Very nicely done... Wow...!!!

That is just awesome, and by the way, it will look perfect on a flared Escort.

What an excellent work...

May I summarize the working principle, to see if I understood it ?

Seen from rear :
- The left crown is simply screwed on the axle
- The right crown is fixed on the drive pulley and both are fixed on the hub
- This hub runs freely on the axle.
- The FAAS gear runs freely on the axle.
- There are three pinions installed.

If I am right, one final question - how did you fix the pinions in the gear ? Did you solder in their tiny shaft protrusions ? Or did you use the old trick with hammer and center punch ?
